Inter-cell Interference Mitigation through Flexible Resource Reuse in OFDMA based Communication Networks
نویسندگان
چکیده
The inter-cell interference problem is a key issue in OFDMA-based mobile cellular networks. In order to deal with this problem, several flexible radio resource reuse schemes for the downlink are examined in this paper. The goal is to improve the cell edge throughput as well as the average cell throughput, compared to a network with frequency reuse factor 1. The cell capacity under those reuse schemes is estimated and compared. Performance in realistic packet-switched networks is also evaluated and compared by extensive system-level simulations.

A Hybrid Inter-Cell Interference Mitigation Scheme for an OFDMA Downlink System
A number of inter-cell interference coordination schemes have been proposed to mitigate the inter-cell interference problem for orthogonal frequency division multiple access (OFDMA) systems and among them, partial frequency reuse is considered one of the most promising approaches. In this paper, we propose an inter-cell interference mitigation scheme for an OFDMA downlink system, which makes us...

Inter Cell Interference (ICI) still poses a real challenge that limits the Orthogonal Frequency Division Multiplexing Access (OFDMA) system performance, especially for users located at the cell edge. A common Inter Cell Interference Coordination (ICIC) technique is interference avoidance in which the allocation of the various system resources (e.g., time, frequency, and power) to users is contr...

This paper analyses the performance of the multi cell OFDMA system for the average spectral efficiency and the coverage probability. We form the Chunk by the grouping of the adjacent subcarriers by exploiting the correlation among them. Frequency band allocation is based on the chunk instead of the subcarrier in order to reduce complexity in the sub carrier based resource allocation. In order t...
